Freddie Mac
Company Overview
Freddie Mac (Federal Home Loan Mortgage Corporation) is one of two government-sponsored enterprises (GSEs) — alongside Fannie Mae — created by Congress in 1970 to support the U.S. housing market. Its core business model is financial intermediation: it buys qualifying mortgages from banks and other lenders, packages them into mortgage-backed securities (MBS), guarantees those securities with its own credit, and sells them to capital markets investors. This releases bank capital to originate more loans, expanding homeownership access.
As a GSE, Freddie Mac enjoys an implicit government guarantee — markets widely assume that if it faced distress, the federal government would intervene. This "too big to fail" status gave it ultra-low borrowing costs, constituting a unique form of competitive advantage. However, it also exposed the company's decisions to deep political influence. In the 2008 financial crisis, Freddie Mac suffered catastrophic losses as the mortgage market collapsed and was placed into federal conservatorship, where it remains today.
Investment Story
1988: Major Purchases. Buffett announced in the 1988 letter that Berkshire "made major purchases of Federal Home Loan Mortgage ('Freddie Mac') preferred stock and Coca-Cola." His thesis was based on three key judgments: Freddie Mac's ultra-low funding costs and implicit government backing; the large, stable growth of the home mortgage market; and the company's high profitability and return on capital. He stated a long-term holding intent: "When we own portions of outstanding businesses with outstanding managements, our favorite holding period is forever."
1988–1999: Building a Large Position. Berkshire's Freddie Mac position grew from an initial ~2.4 million preferred shares to eventually ~60.3 million common shares. By 1995, Berkshire held 12.5 million shares at a cost of $260 million with a market value of $1.044 billion — roughly a 4x return. By 1998, the 60.3 million shares had a cost basis of $308 million but a market value of $3.885 billion — over 12x return. During this period, Freddie Mac was a core Berkshire holding, mentioned alongside See's Candies and Wells Fargo. Buffett noted the correlated risk: a major Southern California earthquake would simultaneously trigger large catastrophe insurance payouts AND reduce the value of Berkshire's Freddie Mac and Wells Fargo positions.
2000: Decisive Exit. Buffett "sold almost all" Freddie Mac and Fannie Mae shares. The timing proved extraordinarily prescient. Though he did not explain his reasons in detail in the letter, subsequent events suggest he had grown deeply uncomfortable with management behavior and the company's increasingly aggressive risk-taking strategies — expanding beyond its core government-backed model into riskier mortgage products.
2003: Fraud Confirmed. Freddie Mac disclosed "mind-boggling" accounting fraud. Buffett cited it in the 2003 letter as evidence of derivatives dangers: "No matter how able and diligent the auditors, no matter how able and diligent the directors, once you get into the derivatives thicket you can't possibly understand" the risks embedded in the positions.
2008: Government Takeover. Freddie Mac and Fannie Mae collapsed in the financial crisis and were seized by the federal government. Buffett wrote sharply: "Derivatives allowed Fannie Mae and Freddie Mac to report large — and largely phony — profits for years. The vehicles that enabled this sleight of hand were complex derivatives contracts that neither their managements nor their regulators fully understood." More than 100 dedicated regulatory employees missed the fraud entirely.
Buffett's Own Words
In 1988 we made major purchases of Federal Home Loan Mortgage Pfd. (“Freddie Mac”) and Coca Cola. We expect to hold these securities for a long time. In fact, when we own portions of outstanding businesses with outstanding managements, our favorite holding period is forever. We are just the opposite of those who hurry to sell and book profits when companies perform well but who tenaciously hang on to businesses that disappoint. Peter Lynch aptly likens such behavior to cutting the flowers and watering the weeds.

For example, See's, Wells Fargo and Freddie Mac could be hit hard. All in all, though, we can handle this aggregation of exposures. In this respect, as in others, we try to "reverse engineer" our future at Berkshire, bearing in mind Charlie's dictum: "All I want to know is where I'm going to die so I'll never go there." (Inverting really works: Try singing country western songs backwards and you will quickly regain your house, your car and your wife.) If we can't tolerate a possible consequen
Investment Lessons
Management character is observable before disaster strikes. Buffett exited Freddie Mac years before the fraud was publicly confirmed. The signals were in management behavior — aggressive accounting, mission creep beyond the core GSE business, excessive use of derivatives to smooth reported earnings. Watching how management acts at the edges — when no one is watching closely, when they face performance pressure — reveals character before it becomes headline news.
Government-sponsored "moats" are uniquely fragile. Freddie Mac's competitive advantage derived from its government charter, not operational excellence or genuine customer loyalty. This created a dangerous dynamic: management could take enormous risks knowing the government backstop limited personal downside, while shareholders bore the ultimate cost. A moat built on regulatory privilege rather than genuine competitive superiority is always vulnerable to political change.
Derivatives opacity destroys intrinsic value estimation. The entire premise of Buffett's investing methodology is estimating a business's intrinsic value with reasonable confidence. When management uses complex derivatives positions to manage reported earnings — positions that neither management nor regulators fully understand — rational value estimation becomes impossible. This opacity, rather than any proximate financial judgment, was the decisive factor in Buffett's exit.
Correlated risks compound portfolio vulnerability. Buffett's awareness that a Southern California earthquake would simultaneously damage his insurance businesses AND his Freddie Mac/Wells Fargo positions illustrates sophisticated portfolio thinking. It also shows why he doesn't focus on single-name concentration risk but thinks about what scenarios would create correlated losses across multiple holdings simultaneously.
